Description

[0001] Technical field: The present invention belongs to the field of flight.

[0002] Background technology: Traditional helicopters or coaxial helicopters cannot use the bending of the main shaft or tilting of the entire rotor disc to control the direction or propel the main body. Traditional helicopters or coaxial helicopters use a main shaft to hoist the main body in the middle position, and the flow of goods and personnel can easily cause the main body to tilt. The left and right tilt-rotor helicopters have wide lift wings that are horizontally wide. When they land and take off, they are tilted at 90 degrees with the main body to maintain the balance of the main body, causing power self-damage. Traditional wings are horizontal, with large resistance, and the chine wing is the longitudinal width plus length. Some traditional rotor discs can only swing in two relative directions and cannot swing in any direction, so they are not flexible and safe. The delta wings of delta wings or powered delta wings cannot be folded during takeoff and landing, unfolded during forward flight, or they cannot take off and land vertically. The vertical rod under the bamboo dragonfly is the role of the sinker. When taking off and landing vertically, the vertical rod has a certain length to keep the main body in a vertical and stable posture. When it is thrown far away by rotation, the shorter the vertical rod below, the farther its flight distance. The principles of stone arch bridges and bows are somewhat similar. The bells on traditional horse-drawn carriages and ox-drawn carts, as well as car horns and lighting instruments, are for safety warnings, in order to ensure the safety of oneself and others.

For the electrically driven one, it has a framework and wires but still belongs to the coaxial type. The horizontal bar above the "T"-shaped coaxial structure is called the horizontal axis bar, and the vertical bar below, which is connected to the main body, is called the vertical axis bar.

[0017] 4. The Two-Pole Gyro Helicopter is a small helicopter for single or a small number of people. It utilizes a "T"-shaped coaxial structure. For the electrically driven type, it has a framework and wires but still belongs to the coaxial type. The horizontal bar above the "T"-shaped coaxial structure is called the horizontal axis bar, and the vertical bar below, which is connected to the main body, is called the vertical axis bar. The upper tilting rotors of the coaxial revolution paddle π are installed at the left and right ends of the upper horizontal axis bar above. This enables the rotor disk to tilt in any direction to change the traveling direction.
